LCP12

LCP12 Protection IC for ringing SLICs SO-8 wide LCP12 Features Protection IC recommended for ringing SLICs Wide firing voltage range: -120 V to +120 V Low gate triggering current: IG = 5 mA max Peak pulse current: IPP = 50 A (10/1000 µs) Holding current: IH = 150 mA min. Applications Dual battery supply voltage SLICs Central office (CO) Private branch exchange (PBX) Digital loop carrier (DLC) Digital subscriber line access multiplexer (DSLAM) Fiber in the loop (FITL) Wireless local loop (WLL) Hybrid fiber coax (HFC) ISDN terminal adapter Cable modem TM: Trisil is a trademark of STMicroelectronics Datasheet − production data Description The LCP12 has been developed to protect SLICs operating on both negative and positive battery supplies, as well as high voltage SLICs. It provides crowbar mode protection for both TIP and RING lines. The surge suppression is assumed for each wire by two thyristor structures, one dedicated ...
